仿照SQL取出flag==true的物件

success: function(res) {
      console.log(res);
      const showHospital = res.filter(function(element) {
        return element.flag == true
      })
      }
 

完整版

function his_data() {
      $.ajax({
        url: '<?php echo site_url('HIS/GetHIS'); ?>',
        method: 'get',
        dataType: 'json',
        success: function(res) {
          console.log(res);
          const showHospital = res.filter(function(element) {
            return element.flag == true
          })
          console.log(showHospital)
          renderHeaderRow(showHospital); //渲染標題列的內容(2間醫院)
          renderRowOptions(showHospital); //渲染標題列的下拉式選單(之後醫院會增加)
          changeHospital(showHospital); //標題列下拉之後改變醫院的標題
          Object.keys(showHospital[0]).forEach(element => {
            if (element != 'id' && element != 'attribute' && element != 'title')
              renderFixedItems(showHospital, element);
          });
          renderColValues(showHospital);
          // addItem(res); //增加項目欄位
          // changeItem(res); //依據項目欄位改變內容
        },
        error: function(err) {
          console.log(err)
        },
      });
    }
